Materials and methods for killing nematodes and nematode eggs

ABSTRACT

Methods and compositions for the control of nematodes are disclosed. Specifically, the subject anthelmintic compounds (substituted 4-phenoxy-6-amino- pyrimidines) have been found to advantageously control animal parasitic nematodes and plant parasitic nematodes at concentrations which are non-phytotoxic. The anthelmintic compounds can be used in conjunction with other nematicidal agents such as B.t.s, avermectins, ivermectin, and milbemycin.

CROSS-REFERENCE TO A RELATED APPLICATION

[0001] This application claims the benefit of U.S. Provisional Application No. 60/179,005, filed Jan. 28, 2000.

BACKGROUND OF THE INVENTION

[0002] Nematodes are important plant pests which cause millions of dollars of damage each year to turf grasses, ornamental plants, and food crops. Efforts to eliminate or minimize damage caused by nematodes in agricultural settings have typically involved the use of soil fumigation with materials such as chloropicrin, methyl bromide, and dazomet, which volatilize to spread the active ingredient throughout the soil. Such fumigation materials can be highly toxic and may create an environmental hazard. Various non-fumigant chemicals have also been used, but these, too, create serious environmental problems and can be highly toxic to humans.

[0003] The accepted methodology for control of nematodes afflicting animals has centered around the use of the drug benzimidazole and its congeners. The use of these drugs on a wide scale has led to many instances of resistance among nematode populations (Prichard, R. K. et al. [1980] “The problem of anthelmintic resistance in nematodes,” Austr. Vet. J. 56:239-251; Coles, G. C. [1986] “Anthelmintic resistance in sheep,” In Veterinary Clinics of North America: Food Animal Practice, Vol 2:423-432 [Herd, R. P., Eds.] W. B. Saunders, New York).

[0004] The pesticidal activity of avermectins is well known. The avermectins are disaccharide derivatives of pentacyclic, 16-membered lactones. They can be divided into four major compounds: A_(1a), A_(2a), B_(1a), and B_(2a); and four minor compounds: A_(1b), A_(2b), B_(1b), and B_(2b).

[0005] The organism which produces avermectins was isolated and identified as Streptomyces avermitilis MA-4680 (NRRL-8165). Characteristics of the avermectin producing culture and the fermentation process are well documented and known to those skilled in the art (Burg, R. W. et al. [1979] “Avermectins, New Family of Potent Anthelmintic Agents: Producing Organism and Fermentation,” Antimicrob. Agents Chemother. 15(3):361-367). The isolation and purification of these compounds is also described in U.S. Pat. No. 4,310,519, issued Jan. 12, 1982.

[0006] Another family of pesticides produced by fermentation are the milbemycins, which are closely related to the avermectins. The milbemycins can be produced by a variety of Streptomyces and originally differed from the avermectins only in the C-13 position. The milbemycins and their many derivatives are also well known to those skilled in the art and are the subject of U.S. patents. See, for example, U.S. Pat. No. 4,547,520.

[0007] While the avermectins were initially investigated for their anthelmintic activities, they were later found to have other insecticidal properties, although the degree varies. The activity of avermectins must generally be determined empirically.

[0008] 22,23-dihydroavermectin B₁ is a synthetic derivative of the avermectins and has been assigned the nonproprietary name of ivermectin. It is a mixture of 80% 22,23-dihydroavermectin B_(1a) and 20% 22,23-dihydroavermectin B_(1b). Ivermectin has been tested on a variety of laboratory and domestic animals for control of nematodes, ticks, and heartworms.

[0009] Avermectin B_(2a) is active against the root-knot nematode, Meloidogyne incognita. It is reported to be 10-30 times as potent as commercial contact nematicides when incorporated into soil at 0.16-0.25 kg/ha (Boyce Thompson Institute for Plant Research 58th Annual Report [1981]; Putter, I. et al. [1981] “Avermectins: Novel Insecticides, Acaracides, and Nematicides from a Soil Microorganism,” Experientia 37:963-964). Avermectin B_(2a) is not toxic to tomatoes or cucumbers at rates of up to 10 kg/ha. Avermectin B₁ is a combination of avermectin B_(1a) (major component) and avermectin B_(1b). It has demonstrated a broad spectrum of insecticidal activities. The data indicate that avermectin B₁ is primarily a miticide, although it is also effective on the Colorado potato beetle, potato tuberworm, beet armyworm, diamondback moth, gypsy moth, and the European corn borer.

[0010] The use of avermectins in various agricultural applications has been described in publications and patents. The use of avermectin with spray oils (lightweight oil compositions) has been described. See, for example, U.S. Pat. No. 4,560,677 issued Dec. 24, 1985; EPO applications 0 094 779 and 0 125 155; and Anderson, T. E., J. R. Babu, R. A. Dybas, H. Mehta (1986) J. Econ. Entomol. 79:197-201.

[0011] There is a continuing need for new, alternative materials and methods useful for killing nematodes.

DETAILED DISCLOSURE OF THE INVENTION

[0173] The process of the subject invention concerns the use of certain organic compounds to control the infestation of plants or animals by nematodes. These organic compounds comprise Formulae I, II, III, IV, and V, as well as structures 44, 45, and 46. In a particularly preferred embodiment of the subject invention, the anthelmintic compound is selected from the group consisting of Compounds 1-46 represented by Structures 1-46. Particularly preferred is the compound represented by Structure 32, and compounds related thereto as represented by Structure 47 depicted in FIG. 47, and as further exemplified by Structures 48-118 depicted in FIGS. 48 through 118. Preferred anthelmintic compounds useful in accord with the subject invention are represented by Structure 47, wherein

[0174] R₁ is H; C₁₋₅ alkyl; halogen; NOC₁₋₅; aryl (optionally substituted with halogen, phenyl, OC₁₋₅ alkyl, or halogenated C₁₋₅ alkyl); OC_(1-5;) COAr; or heterocycle (optionally substituted with C₁₋₅ alkyl);

[0175] R₂ is H; C₁₋₅ alkyl; halogen; NOC_(1-5;) aryl (optionally substituted with halogen, phenyl, OC₁₋₅ alkyl, or halogenated C₁₋₅ alkyl); OC₁₋₅; COAr; or heterocycle (optionally substituted with C₁₋₅ alkyl);

[0176] or R₁ and R₂ form an aryl, heteroaryl, or heterocycle which, optionally, is a component of a multicyclic group which further comprises an aryl group;

[0177] R₃ is H; aryl or heteroaryl (either of which is optionally substituted with halogenated C₁₋₅ alkyl, phenyl or halogen); C₃₋₁₂ cycloalkyl; or C₁₋₂₀ straight or branched alkyl which is optionally substituted with aryl (optionally substituted with halogenated alkyl or halogen);

[0178] R₄ is H; aryl or heteroaryl (either of which is optionally substituted with halogenated C₁₋₅ alkyl, phenyl or halogen); C₃₋₁₂ cycloalkyl; or C₁₋₂₀ straight or branched alkyl which is optionally substituted with aryl (optionally substituted with halogenated alkyl or halogen);

[0179] or R₃ and R₄ form a heterocycle which is optionally a component of a multicyclic group (which further comprises an aryl group) wherein said heterocycle is optionally substituted with C₁₋₅ alkyl, NOC, or COOC₁₋₅.

[0180] Generally, the anthelmintic compounds of the subject invention can be unsubstituted or substituted, saturated or unsaturated. The anthelmintic component of an anthelmintic composition used according to the subject invention may be a single anthelmintic compound or a mixture of two or more anthelmintic compounds. The subject compounds may be used in conjunction with other anthelmintic compounds, including the free acids and salts of the anthelmintic compounds of the present invention. The salts may be, for example, sodium or potassium salts, or ammonium salts. As would be apparent to the ordinary skilled artisan, physiologically acceptable acids and salts of the subject anthelmintic compounds can readily be made and used in accord with the teachings herein, and are hereby expressly included by reference to each compound or group of compounds. For example, “Compound AKC 340” or “Structure 48” is intended to include the physiologically acceptable acids and salts thereof.

[0181] Anthelmintic compounds specifically exemplified herein include Compounds 1-46 represented by Structures 1-46 above, and Compounds 48-118 represented by Structures 48-118 depicted in FIGS. 48-118.

[0182] The subject compounds used in the invention can be applied to animals, the living and feeding areas of animals, plants, or to the situs of plants needing nematode control. The anthelmintic compositions may be applied by, for example, drip and drench techniques. With the drip application, the subject compositions can be applied directly to the base of plants or to the soil root zone. The composition may be applied through already existing drip irrigation systems. This procedure is particularly applicable for ornamental plants, strawberries, tomatoes, potatoes, grapes, and vegetables. Alternatively, a drench application can be used. For treating plants, a sufficient quantity of the anthelmintic composition is applied such that the composition drains to the root area of the plants. An important aspect of the subject invention is the surprising discovery that certain 4-phenoxy-6-amino-pyrimidine compounds have excellent nematicidal activity at concentrations which are not phytotoxic.

[0183] The drench technique can be used for a variety of crops and for turf grasses. The drench technique can also be used for animals. Preferably, for administration to animals the anthelmintic composition would be administered orally to facilitate activity against internal nematode parasites. The compositions of the subject invention can readily be applied using the teachings provided herein.

[0184] In a preferred embodiment of the subject invention, an anthelmintic compound will be applied as an aqueous microemulsion. As described herein, the concentration of the active ingredient should be sufficient to control the nematode infestation without causing phytotoxicity to the desired plants. The concentration of anthelmintic compound may be, for example, from about 0.0001% to about 2%, preferably from about 0.025% to about 1%, and, most preferably, from about 0.05% to about 0.5%.

[0185] The anthelmintic composition used according to the subject invention can be applied in conjunction with one or more other nematicidal agents. The other nematicidal agent may, for example, be applied simultaneously or sequentially with the anthelmintic. Such other nematicidal agents include, for example, avermectins, the B.t.s, and fatty acids.

[0186] The avermectin compound used according to the subject invention may be any of the avermectins, milbemycins, or derivatives of either, having activity against nematodes. The avermectin's activity will be enhanced when combined with an anthelmintic compound as described herein. Thus, the specific combination of ingredients can be manipulated to provide the optimal composition for a particular application.

[0187] Standard concentrations of avermectins are well known to those skilled in the art. For example, the avermectin compounds can be employed in the combination of the subject invention at concentrations of from about 0.03 to about 110 parts per million (ppm). Preferably, from about 1 to about 5 ppm are employed.

[0188] As would be readily appreciated by a person skilled in the art, the delivery of the subject anthelmintic and/or avermectin compound can be calculated in terms of the active ingredient applied per unit area. For example, the subject anthelmintic may be applied at a rate of about 0.02 lb/acre to about 0.1 lb/acre and, preferably, from about 0.5 lb/acre to about 2 lbs/acre. Similarly, the avermectin product can be applied at a rate of up to about 16 oz. of formulated product (“AVID,” available from Merck) per acre. Preferably, about 4 oz. to about 8 oz. formulated “AVID” per acre would be used. Thus, the avermectin compound can be applied up to about 0.02 lb/acre. Preferably, the rate of avermectin is between about 0.005 lb/acre and 0.01 lb/acre. A person of ordinary skill in the art would readily appreciate that the desired application rate of the active ingredients could be achieved using a great variety of different concentrations of active ingredients while varying the application rate of the solution. Thus, a large quantity of dilute solution could be applied or a smaller quantity of a more concentrated solution.

[0189] A variety of different avermectins or related compounds can be used according to the subject invention. Ivermectin may also be used according to the subject invention, as may the milbemycins. For brevity, the term “avermectin” is used herein to refer to all the avermectins and their derivatives as well as related compounds such as the milbemycins and the ivermectins. “Derivatives” refer to chemical modifications of the avermectins or milbemycins which are well known and available to those skilled in this art. Such derivatives are described, for example, in U.S. Pat. No. 4,560,677. Avermectin is readily available under a variety of tradenames including “AVID,” “ZEPHYR,” “VERTIMEC,” and “AGRI-MEK.”

[0190] The anthelmintic compositions of the subject invention may also be used in conjunction with nematicidal agents other than the avermectins. For example, the anthelmintic compounds may be used with biological agents such as Bacillus thuringiensis or with nematicidal fungi. In this context, the anthelmintic composition could be applied at concentrations which would not antagonize the action of the biological agent. The biologically active agent may be in a live proliferative form or may be in a dead stabilized form as described, for example, in U.S. Pat. Nos. 4,695,462 and 4,695,455. Furthermore, the anthelmintic compositions of the subject invention may be used with plants which are specifically bred or engineered for nematode resistance. The plants may, for example, be transformed with B.t. genes which confer nematode resistance or may simply be hybrids or varieties selected for such resistance. The anthelmintic compositions of the subject invention are particularly effective against free- living ectoparasitic nematodes and, therefore, combined use with plants selected for endoparasitic nematode resistance is highly advantageous.

[0191] The subject invention further relates to the surprising discovery that the anthelmintics of the subject invention have ovicidal activity against nematode eggs. Thus, in another embodiment, provided are methods for killing the eggs of nematodes, including those within cysts or egg masses that are commonly formed by Heterodera, Globodera, and Meloidogyne (cyst and root-knot) species.

[0192] The ovicidal compositions according to the subject invention are particularly useful for preplant applications in nematode-control schemes. In addition, the ovicidal compositions of the subject invention can be advantageously used as postplant nematicides, especially because of their relatively low phytotoxicity. In the latter embodiments, ovicidal compositions of the subject invention can be delivered, after planting and at appropriate, essentially non-phytotoxic concentrations of anthelmintic compounds, along with irrigation water and/or plant nutrients to ensure a continuous zone of nematode protection to the enlarging plant root mass. Thus, when applied using these techniques, which include drench or drip systems as are known in the art, phytopathogenic nematodes in their vermiform (wormlike) and egg stages are controlled.

[0193] Anthelmintic compounds having Formulae I, II, III, IV, and V, Structure 47 and most preferably structures 1-46, and particularly Structure 32 and Structures 48-118, are used in preferred embodiments for killing nematode eggs. In addition, microemulsions of the subject compounds are highly preferred for ovicidal applications. In preferred embodiments, the anthelmintic compound(s) will be present in a concentration of greater than about 150 ppm. More preferably, the concentration will be greater than about 200 ppm; most preferably it will be about 250 ppm or more. For certain conditions, the anthelmintic compounds should be applied at high concentrations of about 1,000 ppm to about 5,000 ppm or more.

[0194] In light of the subject disclosure, one skilled in the art could readily, use a variety of application techniques and formulations to prevent the hatching of nematode eggs in a variety of agricultural, farm-related, and garden-related settings.

[0263] It has been found that helminth, acarid and arthropod endo- and ectoparasitic infestations may be controlled, prevented or eliminated, by applying to, injecting or orally dosing said animals with an endo- or ectoparasiticidally effective amount of the subject anthelmintic compounds, preferably the above-described structure 1-46 compounds. This may be achieved by applying the compound to the skin, hide and/or hair of the animals, or injecting or orally dosing said animals with a solid or liquid formulated composition.

[0264] For control of flea infestations, treatment of the infested animal to control adults in conjunction with treatment of the area occupied by the infested animal to control flea larvae is recommended. The compositions of the present invention may be admixed with suitable carriers for application to interior and/or exterior areas for control of flea larvae.

[0265] The compositions of the present invention may be employed as animal feeds, animal feed premixes or feed concentrates. Feed concentrates and feed premixes, useful in the practice of the invention, may be prepared by admixing about 0.25% to 35% by weight of a subject anthelmintic compound, preferably a structure 1-46 compound, with about 99.75% to 65% by weight of a suitable agronomic carrier or diluent. Carriers suitable for use include 0.75% to 35% by weight of a physiologically acceptable alcohol such as benzyl alcohol, phenethyl alcohol or propylene glycol, 0 to about 10% by weight of a vegetable oil such as corn oil or soybean oil, or propylene glycol and about 30% to 95% by weight of a sorptive, edible organic carrier such as corn grits, wheat middlings, soybean meal, expanded corn grits, extracted corn meal or the like or a sorptive silica or a silicate. These feed premixes or concentrates may be admixed with the appropriate amount of animal feed to provide the animals with about 0.5 ppm to 1000 ppm and preferably about 1 ppm to 500 ppm of the compound in the animal's diet. These premixes or concentrates may also be used as top dressings for the animal's daily ration and applied across the top of the daily ration in sufficient amount to provide the animal with about 0.5 ppm to 1,000 ppm and preferably about 1 ppm to 500 ppm of the active ingredient, based on the animal's total feed.

[0266] The subject anthelmintic compounds, and particularly the structure 1-46 compounds, most particularly Structure 32 and Structures 48-118 compounds, may be administered to the animals in or with their drinking water.

[0267] The compound may also be administered in the form of a pill, tablet, bolus, implant, capsule, or drench, containing sufficient anthelmintic compound to provide the treated animal with about 0.01 mg/kg to 100 mg/kg of animal body weight per day of the compound. These dosage forms are prepared by intimately and uniformly mixing the active ingredient with suitable finely divided diluents, fillers, disintegrating agents and/or builders such as starch, lactose, talc, magnesium stearate, vegetable gums, or the like. These unit dosage formulations may be varied with respect to the total weight and content of anthelmintic compound depending upon the kind and size of the animal to be treated, the severity or type of infection encountered and the weight of the host.

[0268] Alternatively, the anthelmintic compound may be administered to animals parenterally, for example, by intraruminal, intramuscular, or subcutaneous injection in which the active ingredient is dissolved or dispersed in a liquid carrier. For this type administration the compound may be dispersed in a physiologically acceptable solvent for subcutaneous injection, or it may be dispersed in a fat or wax or mixture thereof containing an oil, buffer, surfactant, stabilizer, preservative and salt. Components useful in these preparations include carbowax, aluminum monostearate gel, diethyl succinate, soya oil, glyceral dioleate, saline, and capric/caprylic triglycerides.

[0269] The subject anthelmintic compounds may also be applied topically to the larger animals such as swine, sheep, cattle, and horses and companion animals such as dogs and cats in the form of aqueous dips or sprays. For this type administration, the active compound is generally prepared as a wettable powder, emulsifiable concentrate, aqueous flowable, or the like, which is mixed with water at the site of treatment and applied topically to the hide, skin, or hair of the animal. Such sprays or dips usually contain about 0.5 ppm to 5,000 ppm and preferably about 1 ppm to 3,000 ppm of the compound.

[0270] Advantageously, the subject anthelmintic compounds may also be prepared as pour-on formulations and poured on the backs of the animals such as swine, cattle, sheep, horses, poultry, and companion animals to protect them against infestation by nematodes, acarids, and arthropod endo- and ectoparasites. Such pour-on compositions are generally prepared by dissolving, dispersing, or emulsifying the anthelmintic compound in a suitable nontoxic pharmacologically acceptable diluent for pour-on and administration. The diluent must be compatible with the compound and should not be a source of irritation or damage to the animals hide, skin, or hair. Such diluents include vegetable oils, spreading oils, polyhydric alcohols, aliphatic or aromatic hydrocarbons, esters of fatty acids, and lower alkyl ketones.

[0271] A typical pour-on formulation includes about 0.5% to 30% by weight of the anthelmintic compound, about 30% to 60% by weight of an aliphatic or aromatic hydrocarbon, mono or polyhydric alcohol, lower alkyl ketone or mixtures thereof, 0 to about 20% by weight of a vegetable or mineral oil and about 0.5% to 30% by weight of a spreading oil. Another typical pour-on contains about 45% by weight of xylene, about 15% by weight of the anthelmintic compound, about 10% by weight of corn oil or mineral oil, about 25% by weight of cyclohexanone and about 5% by weight of other pharmacologically acceptable spreading agents, antifoam agents, surfactants, or the like.

[0272] The subject anthelmintic compounds may also be prepared as ear tags for animals, particularly quadrupeds such as cattle and sheep. The tags may be prepared by stirring together about 55% to 60% by weight of a vinyl dispersion resin, having an inherent viscosity of about 1.20 and an average particle size of about 0.75 microns, a curing temperature range of about 120° C. to 180° C., with about 28% by weight of butylbenzylphthalate. Stirring is continued, and about 1.5% by weight of ca/Zn stearate stabilizer is added along with about 7.0% of the compound and 2.8% of epoxidized soybean oil. The resulting mixture is deaerated for 15 to 20 minutes at 125 mm/Hg. This mixture can be coated on an ear tag blank by dipping and the resulting tag cured at about 145° C. to 150° C. for about five minutes.

[0273] The compounds of Formulae I-V, Structure 47, particularly Structures 1-46, and particularly Structures 32 and 48-118 are nematicidal and can be used to control nematodes in crop plants. Therefore, in a further preferred aspect of the invention, there is provided a method for killing or controlling nematodes which comprises applying to the locus of the pests or to a plant susceptible to attack by the pest an effective amount of a compound having any of Structures 1-46, preferably Structure 47, and particularly Structures 32 and 48-118, as defined herein.

[0274] The term “controlling” extends to non-lethal effects which result in the reduction or prevention of damage to the host plant or animal and the limitation of nematode population increase. These effects may be the result of chemical induced disorientation, immobilisation, or hatch prevention or induction. The chemical treatment may also have deleterious effects on nematode development, reproduction, or viability.

[0275] The compounds of the invention can be used against both plant-parasitic nematodes and nematodes living freely in the soil. Examples of plant-parasitic nematodes are: ectoparasites, for example Xiphinema spp., Longidorus spp., and Trichodorous spp.; semi-endoparasites, for example, Tylenchulus spp.; migratory endoparasites, for example, Pratylenchus spp., Radopholus spp., and Scutellonema spp.; sedentary endoparasites, for example, Heterodera spp., Globodera spp., and Meloidogyne spp.; and stem and leaf endoparasites, for example, Ditylenchus spp., Aphelenchoides spp., and Hirshmaniella spp.

[0276] The Formulae I-V compounds, Structure 47 compounds, and preferably the compounds of Structures 1-46, more preferably the compounds of Structures 32 and 48-118, display nematicidal activity against different types of nematodes including the cyst nematode. The subject compounds may also be used to combat and control infestations of insect pests such as Lepidoptera, Diptera, Homoptera, and Coleoptera (including Diabrotica i.e. corn rootworms) and also other invertebrate pests, for example, acarine pests. The insect and acarine pests which may be combated and controlled by the use of the invention compounds include those pests associated with agriculture (which term includes the growing of crops for food and fiber products), horticulture and animal husbandry, forestry, the storage of products of vegetable origin, such as fruit, grain and timber, and also those pests associated with the transmission of diseases of man and animals. Examples of insect and acarine pest species which may be controlled by the subject compounds include:

[0310] In order to apply the compound to the locus of the nematode, insect, or acarid pest, or to a plant susceptible to attack by the nematode, insect, or acarid pest, the compound is usually formulated into a composition which includes in addition to at least one of the subject anthelmintic compounds suitable inert diluent or carrier materials, and/or surface active agents. Thus, in two further aspects of the invention there is provided a nematicidal, insecticidal, or acaricidal composition comprising an effective amount of a subject anthelmintic compound and preferably of any of structures 1-46, preferably compounds of Structure 47, more preferably as exemplified by Structures 32 and 48-118, as defined herein and an inert diluent or carrier material and optionally a surface active agent.

[0311] The amount of active ingredient generally applied for the control of nematode pests is from 0.01 to 10 kg per hectare, and preferably from 0.1 to 6 kg per hectare.

[0312] The compositions containing the active ingredient can be applied to the soil, plant or seed, to the locus of the pests, or to the habitat of the pests, in the form of dusting powders, wettable powders, granules (slow or fast release), emulsion or suspension concentrates, liquid solutions, emulsions, seed dressings, fogging/smoke formulations or controlled release compositions, such as microencapsulated granules or suspensions.

[0313] Dusting powders are formulated by mixing the active ingredient with one or more finely divided solid carriers and/or diluents, for example natural clays, kaolin, pyrophyllite, bentonire, alumina, montmorillonite, kieselguhr, chalk, diatomaceous earths, calcium phosphates, calcium and magnesium carbonates, sulphur, lime, flours, talc, and other organic and inorganic solid carriers.

[0314] Granules are formed either by absorbing the active ingredient in a porous granular material for example pumice, attapulgite clays, fullers earth, kieselguhr, diatomaceous earths, ground corn cobs, and the like, or on to hard core materials such as sands, silicates, mineral carbonates, sulphates, phosphates, or the like. Agents which are commonly used to aid in impregnation, binding or coating the solid carriers include aliphatic and aromatic petroleum solvents, alcohols, polyvinyl acetates, polyvinyl alcohols, ethers, ketones, esters, dextrins, sugars, and vegetable oils with the active ingredient. Other additives may also be included, such as emulsifying agents, wetting agents, or dispersing agents.

[0315] Microencapsulated formulations (microcapsule suspensions CS) or other controlled release formulations may also be used, particularly for slow release over a period of time, and for seed treatment.

[0316] Alternatively the compositions may be in the form of liquid preparations to be used as dips, irrigation additives or sprays, which are generally aqueous dispersions or emulsions of the active ingredient in the presence of one or more known wetting agents, dispersing agents or emulsifying agents (surface active agents). The compositions which are to be used in the form of aqueous dispersions or emulsions are generally supplied in the form of an emulsifiable concentrate (EC) or a suspension concentrate (SC) containing a high proportion of the active ingredient or ingredients. An EC is a homogeneous liquid composition, usually containing the active ingredient dissolved in a substantially non-volatile organic solvent. An SC is a fine particle size dispersion of solid active ingredient in water. To apply the concentrates they are diluted in water and are usually applied by means of a spray to the area to be treated. For agricultural or horticultural purposes, an aqueous preparation containing between 0.0001% and 0.1% by weight of the active ingredient (approximately equivalent to from 5-2000 g/ha) is particularly useful.

[0317] Suitable liquid solvents for ECs include methyl ketone, methyl isobutyl ketone, cyclohexanone, xylenes, toluene, chlorobenzene, paraffins, kerosene, white oil, alcohols, (for example, butanol), methylnaphthalene, trimethylbenzene, trichloroethylene, N-methyl-2-pyrrolidone, and tetrahydrofurfuryl alcohol (THFA).

[0318] Wetting agents, dispersing agents, and emulsifying agents may be of the cationic, anionic, or non-ionic type. Suitable agents of the cationic type include, for example, quaternary ammonium compounds, for example cetyltrimethyl ammonium bromide. Suitable agents of the anionic type include, for example, soaps; salts of aliphatic monoesters of sulphuric acid, for example sodium lauryl sulphate; salts of sulphonated aromatic compounds, for example sodium dodecylbenzenesulphonate; sodium, calcium or ammonium lignosulphonate; or butylnaphthalene sulphonate; and a mixture of the sodium salts of diisopropyl- and triisopropylnaphthalene sulphonates. Suitable agents of the non-ionic type include, for example, the condensation products of ethylene oxide with fatty alcohols such as oleyl alcohol or cetyl alcohol; or with alkyl phenols such as octyl phenol, nonyl phenol, and octyl cresol. Other non-ionic agents are the partial esters derived from long chain fatty acids and hexitol anhydrides, the condensation products of the said partial esters with ethylene oxide, and the lecithins.

[0319] These concentrates are often required to withstand storage for prolonged periods and after such storage, to be capable of dilution with water to form aqueous preparations which remain homogeneous for a sufficient time to enable them to be applied by conventional spray equipment. The concentrates may preferably contain 1-85% by weight of the active ingredient or ingredients. When diluted to form aqueous preparations such preparations may contain varying amounts of the active ingredient depending upon the purpose for which they are to be used.

[0320] The subject anthelmintic compounds may also be formulated as powders (dry seed treatment DS or water disperible powder WS) or liquids (flowable concentrate FS, liquid seed treatment LS), or microcapsule suspensions CS for use in seed treatments. The formulations can be applied to the seed by standard techniques and through conventional seed treaters. In use the compositions are applied to the nematodes, to the locus of the nematodes, to the habitat of the nematodes, or to growing plants liable to infestation by the nematodes, by any of the known means of applying pesticidal compositions, for example, by dusting, spraying, or incorporation of granules.

[0321] The compounds of the invention may be the sole active ingredient of the composition or they may be admixed with one or more additional active ingredients such as nematicides, agents which modify the behavior of nematodes (such as hatching factors), insecticides, synergists, herbicides, fungicides or plant growth regulators where appropriate.

[0322] Suitable additional active ingredients for inclusion in admixture with the compounds of the invention may be compounds which will broaden the spectrum of activity of the compounds of the invention or increase their persistence in the location of the pest. They may synergise the activity of the compound of the invention or complement the activity for example by increasing the speed of effect or overcoming repellency. Additionally multi-component mixtures of this type may help to overcome or prevent the development of resistance to individual components.

[0323] The particular additional active ingredient included will depend upon the intended utility of the mixture and the type of complementary action required. Examples of suitable insecticides include the following:

[0324] a) Pyrethroids such as permethrin, esfenvalerate, deltamethrin, cyhalothrin in particular lambda-cyhalothrin, biphenthrin, fenpropathrin, cyfluthrin, tefluthrin, fish safe pyrethroids for example ethofenprox, natural pyrethrin, tetramethrin, s-bioallethrin, fenfluthrin, prallethrin, and 5-benzyl-3-furylmethyl-(E)-(1R,3 S)-2,2-dimethyl-3-(2-oxothiolan-3-ylidenemethyl) cyclopropane carboxylate;

[0325] b) Organophosphates such as profenofos, sulprofos, methyl parathion, azinphos-methyl, demeton-s-methyl, heptenophos, thiometon, fenamiphos, monocrotophos, profenophos, triazophos, methamidophos, dimethoate, phosphamidon, malathion, chloropyrifos, phosalone, terbufos, fensulphothion, fonofos, phorate, phoxim, pyrimiphos-methyl, pyrimiphos-ethyl, fenitrothion, or diazinon;

[0326] c) Carbamates (including aryl carbamates) such as pirimicarb, cloethocarb, carbofuran, furathiocarb, ethiofencarb, aldicarb, thiofurox, carbosulphan, bendiocarb, fenobucarb, propoxur, or oxamyl;

[0327] d) Benzoyl ureas such as triflumuron or chlorofluazuron;

[0328] e) Organic tin compounds such as cyhexatin, fenbutatin oxide, or azocyclotin;

[0329] f) Macrolides such as avermectins or milbemycins, for example such as abamectin, avermectin, and milbemycin;

[0330] g) Hormones and pheromones;

[0331] h) Organochlorine compounds such as benzene hexachloride, DDT, endosulphan, chlordane, or dieldrin;

[0332] i) Amidines, such as chlordimeform or amitraz;

[0333] j) Fumigant agents;

[0334] k) nitromethylenes such as imidacloprid.

[0335] In addition to the major chemical classes of insecticide listed above, other insecticides having particular targets may be employed in the mixture if appropriate for the intended utility of the mixture. For instance, selective insecticides for particular crops, for example stemborer specific insecticides for use in rice such as cartap or buprofezin, can be employed. Alternatively, insecticides specific for particular insect species/stages, for example, ovo-larvicides such as chlofentezine, flubenzimine, hexythiazox, and tetradifon; motilicides such as dicofol or propargite; acaricides such as bromopropylate or chlorobenzilate; or growth regulators such as hydramethylon, cyromazin, methoprene, chlorfluazuron, and diflubenzuron may also be included in the compositions.

[0336] Examples of suitable synergists for use in the compositions include piperonyl butoxide, sesamax, safroxan, and dodecyl imidazole.

[0337] Suitable herbicides, fungicides, and plant-growth regulators for inclusion in the compositions will depend upon the intended target and the effect required.

[0338] An example of a rice selective herbicides which can be included is propanil, an example of a plant growth regulator for use in cotton is “Pix”, and examples of fungicides for use in rice include blasticides such as blasticidin-S. The ratio of the compound of the invention to the other active ingredient in the composition will depend upon a number of factors including type of target, effect required from the mixture, etc. However in general, the additional active ingredient of the composition will be applied at about the rate as it is usually employed, or at a slightly lower rate if synergism occurs.

[0339] The anthelmintic compounds according to the invention also show fungicidal activity and may be used to control one or more of a variety of plant pathogens. In a further aspect the invention therefore includes a method of combating fungi which comprises applying to a plant, to a seed of a plant, or to the locus of the plant or seed a fungicidally effective amount of a compound as herein defined or a composition containing the same. The invention further includes a fungicidal composition comprising a fungicidally effective amount of a compound as herein defined and a fungicidally acceptable carrier or diluent therefor.

[0340] Examples of plant pathogens which the compounds or fungicidal compositions of the invention may control, methods by which fungi may be combatted and the form of suitable compositions, including acceptable carriers and diluents; adjuvants such as wetting, dispersing, emulsifying, and suspending agents; and other ingredients, such as fertilisers and other biologically active materials, are described, for instance, in International application No. WO 93/08180, the content of which is incorporated herein by reference.

EXAMPLE 1 Preparation of Anthelmintic Compounds 1-46

[0343] The anthelmintic compounds of the subject invention can readily be produced using procedures well known to those skilled in the art.

[0344] A variety of anthelmintic compounds useful according to the subject invention can be readily prepared by a person skilled in this art having the benefit of the subject disclosure.

EXAMPLE 2 Nematicidal Activity of Anthelmintic Compositions 1-31

[0345]Caenorhabditis elegans adults were grown on Nematode Growth Medium (NGM) until they produced eggs, then the adults were removed.

[0346] The eggs were allowed to hatch, and the L1 larvae collected. See The Neniatode Caenorhabditis elegans (1988) Cold Spring Harbor Laboratory Press. Using a Matrix Programmable Pipette, the L1s were distributed into 96-well tissue culture plates, 20 L1 in 50 μl NGM per well. Antibiotic/Antimyotic was added to each well, and 1% by weight E. coli strain HB101. The subject anthelmintic compounds were stored at 5 mM in 100% DMSO. 0.7 μl of compounds 1-31 were added to the left-most column of wells to yield a final concentration of 70 μM in 1.4% DMSO, with 1.4% DMSO only as the control. The compounds were then subjected to 5 more 3-fold dilutions from left to right to yield 6 column concentrations of 70 μM, 23.3 μM, 7.8 μM, 2.6 μM, 0.9 μM, and 0.3 μM. Plates were stored in air-tight Rubbermaid plastic boxes at 20° C. The nematodes had cleared all control wells by day 4, and nematode viability was scored by visual examination under a 100× dissecting microscope on day 5. A visual viability scoring system was used as follows:

WORM VISUAL SCORING GUIDE

[0347] Lethality: Dead only stiff L1s (no movement) Dead (L4) worms are dead, but at a later larval stage L1 majority of worms are L1 (based on size) worms move when plate is tapped L2 majority of worms are L2 (based on size) L3 majority of worms are L3 (based on size) L4 majority of worms are L4 (based on size)

[0348] Partial Penetrance: AD majority of worms are adult #AD 5 adult worms or less

[0349] Broodsize Reductions: B! sterile (0-25 progeny) B low broodsize (25-100 progeny) ˜B moderate broodsize (100-250 progeny) < reduced broodsize (250-500 progeny) OK no effect (˜1000+ progeny)

[0350] If several classes of worms exist in a well, then all classes are scored. If adults are present, then the brood score is also recorded. Thus, “L1/L2” would mean a mixture of L1's and L2's are present in the well. “L4/#AD/B” would mean that a mixture of L4's and adults are resent in the well. The “#AD” would mean that there are 6 or less adults, and the “B” would mean that there were 100 progeny or less.

[0351] The results are reported in Table 1. Column VI has a compound concentration of 70 μM with sequential 3-fold dilutions reported in columns V2, V3, V4, V5, and V6, respectively, such that the V6 concentration was 0.3 μM.

EXAMPLE 6 Preparation of Anthelmintic Compounds 47 as specifically exemplified by compounds 32, and 48-118

[0386] While the anthelmintic compounds of the subject invention can readily be produced using procedures well known to those skilled in the art, the following is a preferred method of producing anthelmintic Compounds 47, and exemplified Compounds 32 and 48-118, as shown in FIGS. 47, 32, and 48-118. The general library scheme resulting in Compounds 47 is depicted in FIG. 119.

[0387] The addition of the phenols to 4,6-dichloropyrimidine was done on a 5 mmol scale in standard glassware under nitrogen atmosphere. Sixteen 4-phenoxy-6-chloropyrimidines were made. On a small scale (0.1 mmol) hydrolysis of the dichloropyrimidine was a problem. Moisture was absorbed during the potassium t-butoxide and t-butanol transfers. Displacement of the second chloro was performed on the Gilson 215 liquid handler in septa capped 2-mi vials. Each of 16 mono-chloropyrimidines was distributed into 48 vials and treated with each of 48 amines. Each reaction mixture was extracted with buffered water in Chem Elut tubes.

[0388] For 4-(2′-naphthoxy)-6-chloropyrimidine, 2-Naphthol (734 mg, 5.1 mmols) was dissolved in 6-ml of warm 2-methyl-2-propanol and under nitrogen was treated all at once with 7.5-ml of a 1.0 M solution of potassium tert-butoxide in 2-methyl-2-propanol. Reaction mixture became opaque. A solution of 4,6-dichloropyrimidine (775 mg, 5.2 mmols) in warm 2-methyl-2-propanol (8.6-ml) was added and the mixture was heated to 35° C. RPHPLC or TLC (1/1 hexane/ethyl acetate) was used to monitor the reaction. After 3 hours, if excess phenol was present then additional 4,6-dichloropyrimidine was added. The mixture was stirred over night. The mixture was then diluted with ether and washed with water (2×). The aqueous layers were combined and extracted with ether. The combined ether layers were washed with brine, dried over magnesium sulfate and concentrated under vacuum. 16 phenols were used. 4-pyridone failed to give a good yield of clean material under these conditions.

[0389] The library was made in two sets of 384 compounds on the Gilson 215 Liquid Handler. Fifteen 4-chloro-6-phenoxy-pyrimidines (5 mmoles made up to 10-ml) were dissolved in dichloroethane (DCE). The 8-hydroxy quinoline (ACD 6807) derivative was dissolved in 6-ml DCE and made up to 10-ml with acetonitrile and kept at 35° C. Each chloropyrimidine solution (200 μl, 0.1 mmol) was transferred to each of 24 septa capped 2-ml vials held in four 16×6 Gilson racks. The vial caps were loosened and the solvent evaporated under vacuum at 40° C. for 20 hours. Each of 24 amines (4 mmoles) was combined with 4 mmols (556 μl) of triethyl amine and diluted to 5.5-ml with a 9/1 mixture of 2-methyl-2-propanol/DCE. Each amine (300 μl, 0.218 mmol) was transferred to 16 vials containing the different monochloropyrimidines. The racks were heated to 85° C. for 72 hours. The vials treated with sec-butyl amine (ACD 8094) and cyclohexyl amine (ACD 1486) were retreated with amine and heated for 24 hours. The test library results indicated that these volatile amines evaporated before complete reaction.

[0390] The reaction vial caps were loosened and the solvent was evaporated under vacuum at 40° C. Chem Elut columns (3 cc) were treated with 300μl of 1N hydrochloric acid. The “Chem Elut” columns for ACD6367, ACD9819, ACD6412 and ACD 6216 were treated with water in place of acid. The reaction mixture was dissolved in 400 μl chloroform and transferred by the Gilson 215 Liquid Handler to the “Chem Elut” columns. The columns were eluted with 2-ml of methylene chloride. The solvent was evaporated under vacuum. The library was dissolved in DMSO for plating.

EXAMPLE 8 Sheep Test I Experimental Procedure

[0392] Sheep naturally infected with a variety of gastrointestinal nematodes are purchased from local sources and are transported to the test site. The animals are housed in a manner to preclude further infection by nematode larvae. The animals are evaluated for the presence of adequate nematode burdens by performing a standard fecal egg per gram (EPG) count. Eggs are differentiated into the following groups: trichostrongyle (strongyle), Strongyloides, Trichuris, or Nematodinis. Only sheep judged by the study parasitologist to have adequate nematode infections are retained as test subjects.

[0393] The sheep are fed good quality hay (no concentrated rations) and water ad libitum. Following a five-day acclimation period, the sheep are randomly assigned by EPG count into treatment groups which include non-treated Negative control (placebo); Positive Control (commercially available ivermectin for sheep): and various anthelmintic compounds of the present invention (test compound) dissolved in DMSO. The first replicate of 10 animals is randomly assigned to groups 1-10; the second replicate of 10 animals is randomly assigned to groups 1-10; and the third replicate of 10 animals is randomly assigned to groups 1-10. Thus 10 groups of 3 animals each is created.

[0394] The randomization is performed on fecal samples collected 24-48 hours prior to scheduled treatment. The EPG counts are performed according to Zimmerman Research SOP # NMEPG.99.01

[0395] On treatment day, the animals are weighed and divided into groups with three animals per group as follows:

[0396] GROUP 1: Non-treated negative control (placebo) of 10 ml of DMSO.

[0397] GROUP 2: Positive Control treatment of 200 mcg/kg commercially available ivermectin for sheep.

[0398] GROUP 3: Compound @ dissolved in DMSO.

[0399] GROUP 4: Compound @ dissolved in DMSO.

[0400] GROUP 5: Compound @ dissolved in DMSO.

[0401] GROUP 6: Compound @ dissolved in DMSO.

[0402] GROUP 7: Compound @ dissolved in DMSO.

[0403] GROUP 8: Compound @ dissolved in DMSO.

[0404] GROUP 9: Compound @ dissolved in DMSO.

[0405] GROUP 10: Compound @ dissolved in DMSO.

[0406] The placebo (DMSO), the commercially available drug, and the test anthelmintic compounds are administered in a 3 ml volume by subcutaneous injection using a sterile syringe fitted with a proper needle. The animal is adequately immobilized for injection of the placebo, commercially available drug, or test anthelmintic compound.

[0407] Following treatment, the animals are observed at hourly intervals for the first 8 hours, then daily until necropsy. They will continue to be housed in a manner to prevent further nematode infections. Fecal samples are taken for EPG counts on the 5th day and 7th day after treatment.

[0408] Seven days following treatment the sheep are humanely slaughtered in accordance with the Guide for the Care and Use of Laboratory Animals (DHEW Publication No. 86-23). Necropsy procedures are according to Zimmerman Research SOP # NCRGIH.99.01, Necropsy for Helminth Recovery, specifically for gastrointestinal nematodes. Fecal samples are taken for EPG counts during the sample collection process on this day. All animals are necropsied, but only the animals from the experimental treatment groups that have a significant egg count reduction on day 5 or day 7 will have intestinal material collected for nematode recovery and identification.

[0409] Nematodes are recovered, identified, and enumerated according to Zimmerman Research SOP # NEMRECOVID.99.01. All individuals performing nematode recoveries are blinded to treatment versus control animals. Preliminary estimates of total nematodes recovered from each gut sample are provided prior to identification and enumerations by the study parasitologist. At the discretion of the study parasitologist, seven days after the drug administration fecal egg counts are performed and all animals showing 90% or better trichostrongylid egg reduction will be slaughtered using humane methods recommended by the AVMA. The neck blood vessels are severed and after the animal is completely exsanguinated, the abdomen are opened. The abomasum, the small and large intestines are tied at the omasal and pyloric openings, the duodenum, the end of the small intestine and at the end of the large intestine. Each section is transferred in a separate bucket containing warm water and is slit open and thoroughly washed. The epithelium is inspected before it is removed. The thus prepared washings are saved in gallon jars. An appropriate preservative is added. If preservative is not available, all the intestinal washing should kept in a refrigerator. These washings are passed through a 100-mesh sieve (pore size 149 pm), and the residue is examined for the presence of worms under a dissecting microscope, Lugol's solution may be used to stain the worms. All worms are picked up counted and identified as to the species. An effort should be made to recover any immature forms present. The efficacy should be calculated using the controlled anthelmintic test. ${{Percentage}\quad {efficacy}} = {\frac{\begin{matrix} \left( {{Mean}\quad {number}\quad {of}\quad {worms}\quad {in}\quad {controls}\quad {minus}} \right. \\ \left. {{Mean}\quad {number}\quad {of}\quad {worms}\quad {in}\quad {treated}\quad {animal}} \right) \end{matrix}}{{Mean}\quad {number}\quad {of}\quad {worms}\quad {in}\quad {controls}} \times 100}$

EXAMPLE 9 Sheep Test II Experimental Procedure

[0412] Sheep naturally infected with a variety of gastrointestinal nematodes are purchased from local sources and are transported to the test site. The animals are housed in a manner to preclude further infection by nematode larvae. The animals are evaluated for the presence of adequate nematode burdens by performing a standard fecal egg per gram (EPG) count. Eggs are differentiated into the following groups: trichostrongyle (strongyle), Strongyloides, Trichuris, or Nematodiris. Only sheep judged by the study parasitologist to have adequate nematode infections are retained as test subjects.

[0413] The sheep are fed good quality hay (no concentrated rations) and water ad libitum. Following a five day acclimation period, the sheep are randomly assigned by EPG count into the following treatment groups: Groups 1-9, various anthelmintic compounds of the present invention (test compound) dissolved in DMSO: Group 10, Positive Control (commercially available ivermectin for sheep); Group 11, non-treated Negative control (DMSO only). The first replicate of 1 I animals is randomly assigned to groups 1-1; the second replicate of 11 animals is randomly assigned to groups 1-11; and the third replicate of 11 animals is randomly assigned to groups 1-1. Thus 11 groups of 3 animals each are created.

[0414] The randomization is performed on fecal samples collected 24-48 hours prior to scheduled treatment. The EPG counts are performed according to Zimmerman Research SOP # NMEPG.99.01.

[0415] GROUP 1: AKKADIX compound dissolved in DMSO.

[0416] GROUP 2: AKKADIX compound dissolved in DMSO.

[0424] GROUP 10: Positive Control treatment of 200 mcg/kg commercially available ivermectin for sheep.

[0425] GROUP 11: Non-treated negative control (placebo) of 3 ml of DMSO.

[0426] On treatment day, the animals are weighed, tagged, and divided into groups of three animals per group as follows:

[0427] The placebo (DMSO), the commercially available drug, and the test anthelmintic compounds are administered in a 3 ml volume of DMSO by subcutaneous injection using a sterile syringe fitted with a sterile needle. The site of injection is clipped and swabbed with alcohol prior to injection. The animal is adequately immobilized for injection of the placebo, commercially available drug, or experimental compound.

[0428] Following treatment, the animals are observed at hourly intervals for the first 8 hours, then daily until necropsy. They are housed in a manner to prevent further nematode infections.

[0429] On the fifth day following treatment, fecal samples are obtained from each animal, properly labeled and used for EPG counts.

[0430] Seven days following treatment, all the sheep are weighed and humanely slaughtered in accordance with the Guide for the Care and Use of Laboratory Animals (DHEW Publication No. 86-23). Necropsy procedures are according to Zimmerman Research SOP # NCRGIH.00.01, Necropsy for Helminth Recovery, specifically for gastrointestinal nematodes. Fecal samples are taken for EPG counts during the sample collection process on this day.

[0431] Nematodes are recovered, identified, and enumerated according to Zimmerman Research SOP # NEMRECOVID.00.01. All individuals performing nematode recoveries are blinded to treatment versus control animals.

[0432] Anthelmintic efficacy is calculated using the controlled test procedure: ${\% \quad {Efficacy}} = {\frac{\begin{matrix} {{Mean}\quad {number}\quad {of}\quad {worms}\quad {in}\quad {controls}\quad {minus}} \\ {{{mean}\quad {number}\quad {of}\quad {worms}\quad {in}\quad {treated}}\quad} \end{matrix}}{{Mean}\quad {number}\quad {of}\quad {worms}\quad {in}\quad {controls}} \times 100}$
